Our invention relates to an improvement in window screens shown in the accompanying drawings and more particularly described in the following specification and claims.

One object of the presentinvention isto construct a windowv screen embodying a me tallic frame, with a flange adapted to over- .lap the outer marginal edge of the window casing'to insure a sealing joint between the window casing and the screen frame, whereby the.openingvbounded by the frames'upporting the screen wire may besubstimtially sthe same as the opening bounded-b the 'H' u y wlndow casing thereby providing or a maximum circulation of air through the window-the opening not being contracted. by the screen frame, as in the ordinary ,9 type of window screen construction.

A further advantagegained by constructing the screen frame with arelativel broad flange is that it not only insuresa tig t joint between the screen and the window casing,

. but it also provides for considerable latitude in fitting the screen to window openingswhich frequently vary jconsiderably,espe cially in old houses. l 1

A' further object of the invention consists d in the means employed to lock the frame to the window-casing, thereby insuring a close joint between the screen frame and the window casing and thus overcoming any tend ency of the screen to rattle due; to wind pressure;

A further object of the invention is the reinforcing strips, extending transversely, midway'between the top and bottom of. the screen frame, between which the wire screen extends and'to which it is secured by removable bolts to permit ready renewal of the wire screen when necessary. I

A further object of the invention is the means provided whereby an old "wire screen may be readily removed for replacement whenever necessary. 4 I I A further object of the invention is to pro vide means whereby the screen frame may be swung outwardly for removal, and for washing the windows as required. 4

A further object of the'invention is the means employed for hanging halfj-screen to insure a sealing 'fit' with the upper sash" frame.

A further object of the invention is the w locking bar or fiat wire'femployed to secure the marginal edge of the screen wire in. the grooves formedi jffor its reception in the frame,'-and"whereby the v screen wire is brought under tension,-'-also "the means' for securing Said fiat locking wire in .the groove, and means wherebysaid'locking wire may be readily Qremoved when necessary to" replace the screen wire;

A fu-rther-objectof the invention is :its simplicity andrigidity ofconstructiomalso its low manufacturing costr fthe bar forming the inclosing frame being niitered and bent while cold to form; the corners of'the' frame, or it maybe divided at the corners and welded together as otherwise indicated.

With the foregoingand otherv objects in view which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made inrthe precise embodiment of theinvention herein shown with} out departing from the spirit of'the sameg In th'eldra-wlngs accompanying this specificationi t U Figure 1. is a fragmentary perspective view of the wall, of a building, as seen fromthe outside of the building, showing a window opening,the, casing for the window sash,- and a fragment of the window screen lodged in the opening, with the projecting flanges of the screen frame overlapping the outer wall of the, window casing. n Figure 2'is' a perspective view of the screen suspended from hooks attached to the win-j dow casing,-a fragment of the latter being shown. I t

I denotes the screen wire which in constructing the window screen is laid upon the frame with the marginal edges of the screen wire overlapping the grooves J in the frame of the screen. r is A suitable manually operated tool K having a roller K is now employed to push the screen wire into the groove as indicated in Figure 9, the-roller being manually forced to traverse the screen wire under sufiicient pressure to crowd the screen wire into the groove and against its lower wall.

A flat lockingwire or bar L preferably formed with rounded corners is then inserted in the groove over the wire screen and driven into the groove until the upper surface of the locking bar is below or substantially flush with the face of the frame. To secure the locking bar L against dis placement, a cold chisel, nail-set or other suitabletool is thenemnloved to off-set the wall forming the groove in the frame so as to overlap (h) the locking bar at spaced intervals.

The operation just described is repeated until the four marginal edges'of the screen wire are lodged in the respective grooves of the frame and secured therein by the flat locking wires or bar. The projecting marginal edge of the screen wire is now out off adjacent to the outer surface of the locking bar by a manually operated rotary cutting tool M, the cutting edge of the tool traversing extending from the back of the frame-see' the screen wire adjacent to the locking wire, as indicated in Figure 9. V

N is a reinforcing brace bar extending transversely across the frame and welded or otherwise secured to the side rails. N isa strip of metal overlapping the screen wire and the brace bar, to which it is secured by bolts N The upper bar of the frame is slotted to receive a pair of hooks P P secured to the window casing and to insure a tight joint between the frame and window casing, the frame is slightly off-set above the slotted poltions to receive the shank of the hooks, as indicated at H in Figure 12.

In order that the wire screen may be readily removed from the frame when necessary to replace same with a new screen, holes Je Figure 11-into the grooves J are provided. To remove the wire screen I and the locking bar L from the grooves, anail set or other suitable tool is inserted in the holes J a that it may bear upon the screen and locking bar the nail set is then given a sharp blow witha hammer, thereby dislodging the screen and locking bar from the groove.

To secure the lower ends of the screen frames in the window casings, a pair of'levers R, R are respectively pivoted to the side rails of the frame, having a cam-shaped knife edge R which upon actuating the lever is adapted to force its entrance into the wood casing,-thus securing the frames against rattling or flapping. If metallic window casings are employed, the wall of the casing is indented to receive theedge of the lever.

If a half screen is employed as shown in Figure 4 of the drawings, the frame is supported in a pair of channel members S nailed to the opposing walls of the window casing. To close the opening at the top of the half screen between the screen and the lower rail D of the upper sash frame, an angle plate H is welded or otherwise secured to the upper rail of the screen frame,its projecting flange extending toward the upper sash rail, thereby closing the opening between the screen and sash frames without interfering with either when raised or lowered.

Having thus described our invention, what we claim is:

1. In a window screen, a frame comprising a metallic channel member having a flange integral with its wall extending outwardly from the channel portion, whereby it may overlap the face of a window casing to close the opening between the channel wall of the screen frame and the window casing, said flange punched to provide slots in spaced relation to each other, the wall of said flange above said slots being indented to overlap the shank of supporting hooks, whereby the frame may be in contiguous overlapping relation to the window casing; and a plucation.
